- The most important change is rolling back the incremental
cyclic garbage collector (GC), which was added in one of
the alpha releases. The incremental GC had more significant
performance regressions in specific workloads than we
expected.
- Tests
- gh-124378: Updated test_ttk to pass with Tcl/Tk 8.6.15.
- Library
- gh-124538: Fixed crash when using gc.get_referents() on a
capsule object.
- gh-124498: Fix typing.TypeAliasType not to be generic, when
type_params is an empty tuple.
- gh-123017: Due to unreliable results on some devices,
time.strftime() no longer accepts negative years on
Android.
- gh-123014: os.pidfd_open() and signal.pidfd_send_signal()
are now unavailable when building against Android API
levels older than 31, since the underlying system calls may
cause a crash.
- gh-124248: Fixed potential crash when using struct to
process zero-width ‘Pascal string’ fields (0p).
- gh-87041: Fix a bug in argparse where lengthy subparser
argument help is incorrectly indented.
- gh-124212: Fix invalid variable in venv handling of failed
symlink on Windows
- gh-124171: Add workaround for broken fmod() implementations
on Windows, that loose zero sign (e.g. fmod(-10, 1) returns
0.0). Patch by Sergey B Kirpichev.
- gh-123934: Fix unittest.mock.MagicMock reseting magic

Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
